GrantCee Posted September 20, 2016 Share Posted September 20, 2016 Have run into an issue with TIFF exports which may or may not be related to the El Capitan TIFF issue. Using Beta 5 on El Capitan 10.11.6 I have an image of a B&W film negative. The image is a Lumix RAW file processed in DxO and exported as a TIFF. I've take that TIFF and opened it in AP, applying invert and curves filter layers. I've merged the visible layers and exported as a 16-bit greyscale TIFF using Lanczos resampling. The TIFF displays correctly in Finder and Preview, but when imported into Aperture or Photo Supreme it shows either "unrecognized file type" (Aperture) or simply a black rectangle (Photo Supreme) — which was the behavior of all TIFFs until the tile fix in the 1.5 Beta 4. However, if the image is exported as a 16-bit greyscale using bilinear resampling, it displays correctly in both applications. That led me to try all the other resampling methods, and it turns out that a 16-bit greyscale export using ANY resampling other than bilinear shows the problem.I also tried exporting it as a 16-bit RGB file, and regardless of resampling method the RGB files display properly in both apps. It seems something is broken in the 16-bit greyscale export routine! Link to comment Share on other sites More sharing options...
GrantCee Posted September 23, 2016 Author Share Posted September 23, 2016 Update: I sent a file to the PSu developer who examined it and pronounced it fine. It looks like another instance of not all apps completely adapted to the El Capitan system changes, not a bug in AP. Consider this closed. Link to comment Share on other sites More sharing options...
